WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent N o. 639,831, datedDecember 26, 1899.

Application filed December 1,1898. Serial No. 698,035. (No model.)

To all w7't'07'7t t may 0071.007472:

Be it known that I, GEORGE L. SOovILLE, a citizen of the United States,residingat West Superior, in the county of Douglas and State ofWisconsin, have invented a new and usef u1 Weather-Strip, of which thefollowing isa specification.

My invention relates to improvements in weather-strips of that classwherein a slidable Io strip is Iitted in the recess in the bottom edgeof the door to dispense with a threshold-strip on the door-sill; and thepurpose of the present improvement is to simplify the construction andrender the device efficient and relia- [5 ble in operation, so that onthe closing ofthe door the stri p is positively depressed into firmengagement with the door-sill to exclude the weather. A

Afurtherpurpose of the invention is to prozo vide means by which theslidable strip is de'- pressed positively on closing the door, and suchdepressing Ineans may be adjusted to regulate the extent of adjustmentof the weather-strip to compensate for shrinking of the door and of thesill, and thereby eifect nicety in the adjustment of the strip, so as tosecure proper closure of the space between the door and the sill.

Vith these ends in View the invention consists in the novel combinationof elements and in the construction and arrangement of parts, which willbe hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated thepreferred embodiment thereof in the accompanying drawings, forming apart of this specification, and in which- Figure 1A is a perspectiveview with the door partly open and showing my improved weather-stripapplied thereto. Fig. 2 is a vertical sectional viewin the plane of thejamb and the door, showing the latter closed. Fig. 3 is a verticaltransverse section on the plane indicated by the dotted line 3 3 of Fig.2. Fig. 4 is a detail perspective view of the slidable strip with thesprings attached thereto. Fig. 5 is a detail sectional elevation of thebumper.

Like numerals of reference denote like and corresponding parts in eachof the several figures of the drawings.

10 designates the door-jamb, which is provided with the usual internalbead or shoulder 11, against which the door 12 may press or bear when itis closed, the door being hinged at 13 to the jamb. All of these partsare ordinary in the art, and no novelty therefor is herein claimed.

To accommodate the slidable weather-strip, a recess or channel 14. iscutin the lower edge of the door 12,-and in said recess is snugly fitteda slidable strip 15, which may be made of any suitable material. vThisstrip 15 is suspended lor hung within the recessed lower edge of thedoor by springs, which serve to actuate the strip, thereby dispensingwith means for guiding the strip in its proper play or for connectingthe strip to the door other than by the springs. The strip 15 is capableof a vertical play or movement simultaneous with its endwise movement,and the suspension-springs are arranged to give the proper travel to thestrip when the door is opened, so that the lower edge of the strip willlie practically flush with the corresponding edge of the door when thelatter is opened. The strip is provided with a series of inclined ,slotsin its upper edge, and in the drawings I have represented the slidablestrip as provided with two slots 16 17, which are arranged near therespective ends of the strip and are inclined in the same orcorresponding directions. Each inclined slot is provided with a longface 18 and a short side 19, and each slot terminates at its lower endin a rounded enlargement or eye 20.

The suspension and actuating springs for the slidable strip areindicated by the numerals 2l 21, and these springs are inclined toproperly fit the slots 16 17. Each spring 21 consists of a fiat piece ofelastic metal, which is provided at its lower end with a rounded orspil'ally-bent journal 22 and with a at head 23. The journal 22 of thespring is made by coiling or twisting the lower end of said spring uponitself, and the fiat head 23 of the spring lies at an angle to theinclined spring-shank. The springs are secured within the recess of thedoor by fitting the fiat heads 23 thereof against the lower horizontalface of the door-recess and by passing the screws 24. through thespring-heads 23, so

IOC

that the upper ends of the springs are fastened securely to the door.The inclined shanks of the springs pass through the inclined slots ofthe strip, and the round journals 22 are fitted snugly in the roundedeyes 2O of said strip. The diameters of the eyes 2O in the strip and thejournals 22 of the springs exceed the width ot the slots at the lowerends thereof contiguous to the enlargements or eyes 20, and thisconstruction prevents the journals 22 of the springs from pulling out ofthe slots in the strip. The springs and strip are thus connected for thestrip to be carried or sustained wholly by the springs, and the latterserve to raise the strip when the door is opened for the lower edge ofthe strip to lie practically flush to the corresponding edge of thedoor. The springs, with their upper ends fastened firmly within therecess of the door, are adapted to have their free ends move or travelin an are of a circle in order to impart an endwise movement to thestrip simultaneously with its vertical movement, and as the springs arefixed at one end their twisted journals 22 are adapted to turn slightlyin the enlargements or eyes of the strip-slots without, however,exposing the parts to disconnection one from the other.

In my improved weather-strip the construction is such that it isnecessary to make a single recess in the lower edge of the door,

such recess extending practically the full width of the door and beingof uniform size in cross-section, the lower edge of the door within therecess lying in aplane parallel with the exposed edge of said door. Thisconstruction simplifies the formation of the door for the reception ofthe strip and facilitates the attachment of the springs, because it isonly necessary to fasten one end of each spring directly to a straighttop wall of the recess in the door. Each spring is made from a singlepiece of resilient sheet metal and is bent to forni a rounded journal atone end and the shank at the other end, that portion of the springbetween the shank and the journal being inclined'in order to suspend theweather-strip below the door and to permit said strip to have thenecessary vertical play.

From the foregoing description it will be understood that the springs onopening the door move the slidable strip endwise, so as to project itsinner end beyond the hinged edge of the door, and to effect thedepression of the strip 15 when the door is closed I employ a buinpei25,which is attached to the door-jamb ina position to lie in the path ofthe slidable strip. This bumper consists of a strip or length of springmetal having a slot or fork 26 at one end, and said bumperspring isarranged in a vertical position on the door-jamb to have its upper endfastened securely thereto by a screw 27, which passes through asuit-able opening in said bumperspring and is embedded in the jamb. Thelower forked end of the bumper-spring receives an antifriction-roller28, which is journaled loosely, as at 29, in the free end of saidspring, and this roller is adapted to ride against the end of theslidable strip 15, thus reducing the friction between the bumperspringand the end of the slidable strip. To prevent the bumper-spring fromyielding unduly under the impact or pressure of the spring-controlledstrip 15, I employ an adjust-able stop-screw 30, which is secured in thedoor-jamb at a point between the fastening-screw 27 and thefriction-roller 28. This stop screw offers resistance to the inwardmovement of the bumper-spring under the pressure of the strip 15 whenthe door is closed, and said screw 30 may be adjusted more or less inrelation to the bumper-spring to project the latter at variabledistances from the face of the door-jamb, whereby the bumper may beadjusted to depress the strip 15 more or less, and thus secure nicetyofadjustment of the spring-pressed strip, so as to compensate forshrinkage of the door or sill and effeet the tight closing of the spacebetween the door and sill by the weather-strip. The head ot' thestop-screw 30 is accessible through an opening 31, which is formed inthe bumperspring to permit the operator to introduce the point of ascrew-driver or other implement for engagement with the screw to adjustthe latter; but the diameter of this opening 31 is less than the widthof the screw-head in order that the latter may have proper bearingagainst the bumper-spring to offer resistance tothe inward movement ofthe bumper when the slidable strip presses against the frictionroller,which is carried by the bumper-spring. Changes may be made in the formot' some of the parts while their essential features are retained andthe spirit of the invention enibodied. Hence I do not desire to belimited to the precise form of all the parts as shown, reserving theright to vary therefrom.

Having thus described the invention, what I claim is The combinationwith a door, a rec'essed jamb, an endwise-movable strip confinedslidably on said door and springs connecting the strip to the door, of aslotted bumper-spring attached t-o said jamb and having its free endextended into the recess thereof, a roller mounted in said free end ofthe bumperspring and arranged in position to ride against the end ofsaid movable strip on closure of the door, and an adj Listing-screwiixed to the jamb and bearing against the bumper-spring to adjust thefriction-roller relative to the path of the movable strip, said screwbeing accessible, for adjustment thereof, through the slot in thebumper-spring, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

GEORGE L. SCOVILLE.
